Solution Let S be the number of times that the result was odd, which is a binomial random variable,with n 100andp=0.5, ·so that E[S]=100·0.5=50 。and 0s=V100·0.5·0.5=5Solution • Let 𝑆 be the number of times that the result was odd, which is a binomial random variable, with 𝑛 = 100 and 𝑝 = 0.5, • so that 𝐄[𝑆] = 100 · 0.5 = 50 • and 𝜎𝑠 = 100 · 0.5 · 0.5 = 5
